Herein, we show how conceptually simple oxidative transformations can be used to unlock the inherent reactivity of terpene synthons in generating polyesters by two different mechanisms starting from the same \u03b1-pinene substrate. In the first pathway, \u03b1-pinene was oxidized into the bicyclic verbanone-based lactone and subsequently polymerized into star-shaped polymers via ring-opening polymerization, resulting in a biobased semicrystalline polyester with tunable glass transition and melting temperatures. In a second pathway, polyesters were synthesized via polycondensation, utilizing the diol 1-(1'-hydroxyethyl)-3-(2'-hydroxy-ethyl)-2,2-dimethylcyclobutane (HHDC) synthesized by oxidative cleavage of the double bond of \u03b1-pinene, together with unsaturated biobased diesters such as dimethyl maleate (DMM) and dimethyl itaconate (DMI). The resulting families of terpene-based polyesters were thereafter successfully cross-linked by either transetherification, utilizing the terminal hydroxyl groups of the synthesized verbanone-based materials, or by UV irradiation, utilizing the unsaturation provided by the DMM or DMI moieties within the HHDC-based copolymers. This work highlights the potential to apply an oxidative toolbox to valorize inert terpene metabolites enabling generation of biosourced polyesters and coatings thereof by complementary mechanisms.", "doi": "10.1021/jacsau.1c00312", "pmid": "34849510", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC8620555"}], "notes": [], "created": "2026-08-20T08:45:19.017Z", "modified": "2026-08-20T08:45:19.176Z"}, {"entity": "publication", "iuid": "b9149930663e43008ad85667ff1f72d9", "links": {"self": {"href": "https://publications-affiliated.scilifelab.se/publication/b9149930663e43008ad85667ff1f72d9.json"}, "display": {"href": "https://publications-affiliated.scilifelab.se/publication/b9149930663e43008ad85667ff1f72d9"}}, "title": "Biocatalysis in the Recycling Landscape for Synthetic Polymers and Plastics towards Circular Textiles.", "authors": [{"family": "J\u00f6nsson", "given": "Christina", "initials": "C", "orcid": "0000-0003-3124-1723", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/00a9f7e064a7479aa2dea0e0363b3077.json"}}, {"family": "Wei", "given": "Ren", "initials": "R"}, {"family": "Biundo", "given": "Antonino", "initials": "A"}, {"family": "Landberg", "given": "Johan", "initials": "J"}, {"family": "Schwarz Bour", "given": "Lisa", "initials": "L"}, {"family": "Pezzotti", "given": "Fabio", "initials": "F"}, {"family": "Toca", "given": "Andreea", "initials": "A"}, {"family": "M Jacques", "given": "Les", "initials": "L"}, {"family": "Bornscheuer", "given": "Uwe T", "initials": "UT", "orcid": "0000-0003-0685-2696", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/0464afedde7643f19b28b66fb3497017.json"}}, {"family": "Syr\u00e9n", "given": "Per-Olof", "initials": "PO", "orcid": "0000-0002-4066-2776", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/b035f26bd71e42f9942f9a4943ed0d1a.json"}}], "type": "journal article", "published": "2021-10-05", "journal": {"title": "ChemSusChem", "issn": "1864-564X", "volume": "14", "issue": "19", "pages": "4028-4040", "issn-l": null}, "abstract": "Although recovery of fibers from used textiles with retained material quality is desired, separation of individual components from polymer blends used in today's complex textile materials is currently not available at viable scale. Biotechnology could provide a solution to this pressing problem by enabling selective depolymerization of recyclable fibers of natural and synthetic origin, to isolate constituents or even recover monomers. We compiled experimental data for biocatalytic polymer degradation with a focus on synthetic polymers with hydrolysable links and calculated conversion rates to explore this path The analysis emphasizes that we urgently need major research efforts: beyond cellulose-based fibers, biotechnological-assisted depolymerization of plastics so far only works for polyethylene terephthalate, with degradation of a few other relevant synthetic polymer chains being reported. In contrast, by analyzing market data and emerging trends for synthetic fibers in the textile industry, in combination with numbers from used garment collection and sorting plants, it was shown that the use of difficult-to-recycle blended materials is rapidly growing. If the lack of recycling technology and production trend for fiber blends remains, a volume of more than 3400 Mt of waste will have been accumulated by 2030. This work highlights the urgent need to transform the textile industry from a biocatalytic perspective.", "doi": "10.1002/cssc.202002666", "pmid": "33497036", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC8518944"}], "notes": [], "created": "2026-08-20T06:31:55.037Z", "modified": "2026-08-20T06:31:55.204Z"}]}
